Abstract: A valve arrangement is for a downhole apparatus having a tubular body having first and second ports in a wall thereof. The valve arrangement comprises a valve member that comprises a first port associated with the first port of the tubular body; and a second port associated with the second port of the tubular body. The valve arrangement is configurable to be locked in a first configuration with the tubular body, such that the first port is closed and the second port is closed. The valve arrangement is configurable to be locked in a second configuration with the tubular body, such that the first port is open and the second port is closed. The valve arrangement is configurable to be locked in a third configuration with the tubular body, such that the first port is closed and the second port is open.

Abstract: A method comprising operating a first valve arrangement and a second valve arrangement from a locked first configuration, in which the first port is closed and the second port is closed, to a locked second configuration, in which the first port is open and the second port is closed, wherein the first valve arrangement comprises one or more locking devices configured to lock a first valve member of the first valve arrangement in place relative to the tubular body. The method comprising operating the first valve arrangement and the second valve arrangement from the locked second configuration to a third configuration, in which the first port is closed and the second port is open.

Abstract: Arrangements herein are directed to pin state detection systems and arrangements for using such systems. A pin detection system can include a pin. The pin can be in one of multiple states, such as a depressed state and an undepressed state. The system can include a transmit coil and a receive coil that encircles the pin. The system can also include a processing system that causes a transmit signal to be transmitted to the transmit coil. The processing system can analyze a signal received from the receive coil to determine a state of the pin.

Abstract: A game of chance uses a deck of playing cards which have imprinted thereon a variety of different symbols, such as the symbols that are used on reel strips in reel slot machines. Each player makes a first BET wager and the dealer deals three cards to each player. If the player receives a winning combination on the first three cards, the player proceeds to the draw step and receives a fourth card without having to make an additional wager in order to attempt to improve his hand. If the player does not have a winning combination on the first three cards, the player may optionally make a second DRAW wager and proceeds to the draw step and receives a fourth card in an attempt to improve his hand to a winning combination. The player does not have to discard at any time. The player then uses the best three or four cards after the draw step to make any possible winning combination as shown on a pay table. The player's highest hand is paid on the winning wager only.

Abstract: A deck of playing cards has imprinted thereon different symbols, such as 7's, Bars, Bells, Grapes, Oranges, Melons and Cherries, and optionally a Wild Joker symbol. Each player is playing against a pay table and not against the dealer. Each player makes a first wager and the dealer deals three cards to each player. If the player is dealt three matching symbols, or One or Two Cherries or a Wild symbol, the player achieves a winning combination and is eligible to receive a payout based on the amount of the player's wager. The player may collect his winning amount and end the hand or the player may decline the winning amount, surrender his wager, make a second wager and proceed to the draw step of the method of play. If the player is dealt any pair or three-of-a-kind symbols, the player has the option of proceeding to the draw step or simply standing with his initial first wager winner or loser that was dealt to him.
